1 Claim. 1

This invention relates to water craft.

An object of the invention is to provide water craft .of the characterdescribed having a novel type of chines.

It is another object of the invention to provide, in water craft, chinesof novel formation whose forward ends are united with a novel type ofprow bottom.

The bottom of the prow is divided into sections along a centrallongitudinal line and the chines are connected to the respectivesections, before assembly, or integrally united therewith inconstruction.

With the prow bottom sections united together, along said longitudinalcentral line and with the chines either formed integrally with saidbottom sections or united thereto, the sides of the craft may be moreeasily and accurately assembled in the construction of the craft.

Other objectives and advantages will be apparent from the followingspecification, which is illustrated by the accompanying drawings,wherein Figure 1 is a side elevation of the craft with the chines formedintegrally with the prow bottom sections;

Figure 2 is a bottom plan showing the chines united, at their forwardends, to the corresponding prow bottom sections;

Figure 3 is an enlarged cross-sectional view taken on the line 3-3 ofFigure 2; and

Figure 4 is an enlarged cross-sectional view taken on the line 4--4 ofFigure 2.

Referring more specifically to the drawings, the numerals I, I designatethe Sides of the water craft and the numeral 2 designates the stern.

At the forward end of the craft the sides converge forwardly, formingthe prow 3, and said forward ends also converge downwardly to the outermargins of the prow bottom which, in the present illustration, is formedof sections 4, 4 which are united, in construction, along a longitudinalcentral line. Preferably, their adjacent edges are reversely bevelled soas to overlap, forming the joint 5, said overlapping margins beingsecured together in any preferred manner, preferably with a suitabletype of glue.

The outer margins of the bottom sections 4, 4 are curved upwardly,forming the flanges 6, 6 to the outsides of which the lower margins ofthe sides I, I may be glued or otherwise secured, as indicated in Figure4.

The numerals 'I, I designate the chines which extend from the stern ofthe craft to the rear ends of the bottom sections 4 with which they 2are united, either integrally, as indicated in Figure 1, or to whichthey are secured by glue or in any other approved manner, as shown inFigure 2.

The lower margins of the sides I also overlap the upper margins of thesechines, as shown in Figure 3, and may be secured thereto in any approvedmanner, as by a suitable glue.

These chines are arcuate in cross-section, as more clearly shown inFigure 3, having the upstanding flanges Ia, Ia. to which the sides I aresecured, and also having the inwardly directed bottom flanges 1b, 1bwhich are united with the bottom 8 of the stern of the craft.

The forward ends of the upstanding flanges Ia merge into thecorresponding flanges 6 of the prow bottom sections 4, 4.

The inner margins of the horizontal flanges 1b are united with theadjacent margins of the stern bottom 8. Preferably, these adjacentmargins are reversely bevelled and fitted together and secured togetheras a unit by suitable glue or other securing means.

As hereinabove stated, the novel features of the craft reside in the twochines I, 1, of special formation, which merge into, and are integrallyunited with, the prow bottom sections 4, 4, thus forming two unitswhich, before assembly, may be packed together to occupy small space inshipment and which may be first united together, in construction, toform a convenient framework about which the remainder of the craft maybe easily assembled.

The craft may be made of wood in which case the parts may be joinedtogether by glue, rivets, nails or screws, or in any other preferredmanner; or on the other hand, the craft may be composed of metal such asaluminum, tin, manganese, or any other suitable metal designed for suchpurpose.

If composed of metal the parts may be most practically united byriveting or welding, although they may be united in any other approvedmanner.

What I claim is:

In water craft, complementary prow bottom sections adapted to be unitedalong a longitudinal, approximately central line and whose outer marginsare curved upwardly a stern bottom section united to the prow bottomsection along a transverse line and having beveled side margins, chinesterminating at said transverse line united to said respective outermargins and extending rearwardly therefrom and which are substantiallyarcuate in shape in cross-section,

said chines having upstanding outer portions and inwardly directedbottom portions, the inner margins of the bottom flanges being bevelledthroughout their length and united with said side margins of said sternbottom section.
